The invention relates to an unducted rectifier for a turbomachine comprising: - stator vanes (23) each comprising a root (25) and a blade (24) radially projecting from the root, the root comprising two half-platforms (40A, 40B) extending on either side of the blade, - pivots (32), each associated with a vane (23) mounted so as to pivot about a pitch axis and intended to be connected to a system (34) for changing the pitch of the blades, each pivot comprising an upper platform (50) and a cylindrical lower portion (52), - attachment systems for attaching the half-platforms (40A, 40B) of the root of the vane to the associated pivot, each comprising two plates (62A, 62B) having a substantially identical shape to each half-platform and a clamping system for clamping the half-platforms (40A, 40B) between the plates (62A, 62B) of the attachment system and the upper platform (50) of the pivot.
